Answer:
-20
Step-by-step explanation:
Given the expression 20÷4×1-5²
We are going to use PEMDAS precedence to solve the expression
P is the parenthesis
E is the exponenent
= 20÷4×1-(5²)
= 20÷4×1-25
Folowed by Multiplication
= 20÷(4×1)-25
= 20÷4-25
Followed by Division
= (20÷4)-25
= 5 - 25
Then finally Subtraction
= -20
Hence the result of the expression is -20
